SPECIFICATION forming part of Letters Patent No. 434,340, dated August 12, 1890.

Application filed MarohZQ, 1890.

To all whom it may concern,.-

Be it known that I, EARL H. ISRAEL, of the city of St. Louis, in the Stateof Missouri, have invented a certain new and useful Improvement in Vater-Closets, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specificaion.

My invention relates to certain improve-l ments in water-closets; and my invention consists in features of novelty hereinafter fully described, and pointed out in the claims.

Figure I is a side elevation illustrative of my invention, the cistern or tank being shown in section. Fig. II is a top or plan view, the tank not being shown. Fig. III is a horizontal section taken on line III III, Fig. I. Fig. IV is a vertical section showing the condition of the partsjust after the Siphon is formed and the flush of the bowl (not shown) commenced. Fig. V is a similar view showing the condition of 'affairs after the flushing is completed, the siphon broken, and the refilling of the tank commenced. Fig. VI represents a modification of my preferred form of invention.

Referring to. the drawings, 1 represents a suitable tank or cistern, and 2 part of the pipe leading therefrom to the bowl of the closet.

v3 represents the long leg, and 4 the short leg, of an ordinary siphon arranged within the tank, and the long leg of which communicates with the bowl-pipe 2.

5 represents an ordinaryvalve operated by a lever 6, chain 7, and rod 8, as usual, to open communication between the tank and the long leg of the siphon when the bowl is to be ushed.

9 represents the supply-pipe of the tank, 10 the valve of the pipe, and 11 the float of the valve.

I claim no invention in any of the parts,

per se, thus far mentioned, as they may be of any of the desired forms and constructions now well known in the trade.

13 represents a chamber located in the bottom of the tank or cistern 1, and which has an upwardly-extending air-tube 14, preferably held to the top of the chamber by a neck Serial No.345,821. (Nomodel.)

15 on' the top of the latter, anda set-screw 16, passing through the neck and jamming against the tube. The tube is thus adjusted in height. Within the chamber 13 is a second chamber 17, open at top.

18 represents a pipe leading from the cham'- ber 17 up through the tube 14 and communieating with the upper portion of the Siphon. (See Figs. IV and V.) A space or passageway is left between the pipe 18 and tube 14;

19 represents a short tube or pipe extending from the lower portion of the chamber 13 into the short leg 4 of the siphon.

The operation is as follows: The valve 5 being opened, the siphonic action is formed and the water starts to iiow from the tank up the short leg of the siphon down the long leg of the Siphon into the pipe 2 leading to the bowl. (See arrows, Fig. IV.) The Valve 5, being released as soon as the siphon is formed, closes. While the water is passing from the tank through the siphon, it is also being exhausted from the chamber 13 through the pipe 19 and the siphon, and is also being exhausted from the chamber 17 through the pipe 18 and the siphon, as shown by the arrows in Fig.'IV. The siphon will remain unbroken and the water continue to run from the tank into thebowl until the water lin the chamber 17 is reduced to the lower open end of the pipe 18, and then the air which has passed down the tube 14 into the chambers 13 and 17, as the water was removed, passes up the pipe 18 and breaks the siphon. The duration of flush may be regulated by adjusting the tube 14 up or down, for itis evident that the lower the top of the tubeis beneath the surface ofthe water before the Siphon is started the longer the duration of the flush will be, for the height of this tube. regulates the period of time it takes to empty the chambers 13 and 17, which are filled through this tube when its upper end is, beneath the surface 0f ,the water. As soon as the siphon is broken the water in the short leg of the siphon seeks the level of the water in the tank, (see Fig. V,) the-chambers 13 and 17 being immediately refilled by water pass- ,ing' through the pipe 19, so that the Siphon may again be started.

It will be observed that the chambers 13 IOO and 17 will be filled through the pipe 19, whether or not this pipe extends into the short leg of the Siphon, and the pipe could be located outside the Short leg of the Siphon, (the pipe 18 alone being utilized to drain the chamber when the Siphon is workingg) but I prefer to place the pipe 19 within the short leg of the Siphon, as shown, so that the water in the chamber 13 will be drained (when the Siphon is working) beneath the top of the chamber 17, so that when the Siphon is broken, as described, there will be a Short lapse of time before the water entering through the pipe 19 will iiow into the ,chamberk 17, (it having first to fill the space between the chambers,) so that there iS no liability of the Siphon starting again before enough air enters through the pipe 18 to break it. By an arrangement of this kind a most effective and durable device is produced wherein no valves are employed to get out of order and a uniform action can be implicitly relied upon. The construction, moreover, is comparatively cheap and uncostly.

In Fig. VI, I have shown a modification wherein the chamber 17 and the pipe 18 are omitted and the tube 14 is made Shorter than in my preferred form,.while the pipe 19 is made longer than in my preferred form. In this form of my invention the water enters the chamber 13 through the tube 14, which may be adjusted up or down to make a long or short wash, as desired. When the Siphon is Started, and after it has reduced the water in the cistern to the level of the upper end of the tube 14, the water is exhausted from the chamber 13 by the pipe 19, air entering the chamber through the tube la as the water is exhausted. Vhen the water is exhausted from the chamber, the air enters through the pipe 19 into and breaks the siphon. Then, as the eistern is refilled through the valve 10, the chamber 13 is refilled through the tube 14. This form of my invention may be used where but a Single wash is wanted at a time and a wash of a practically xed duration.

In washout and Siphon closets it iS desirable to retain in the bowl after each fiush a body of water. I have devised a very cheap and effective means for maintaining a Supply of water in the bowl, and it consists of a cylinder or cylinders 20, arranged within the tank or cistern and provided with an open-ended pipe 21 extending from its bottom to near its top. The tube communicates at bottom with the long leg of the Siphon through means of a small pipe 22 and at top through means of a larger pipe 23. Now when the Siphon iS started the action of the water. fiowing through the Siphon produces a partial vacuum in the cylinder 2O and the water immediately iiows through the pipe 21 and fills the cylinder. The pipe 23 being much larger than the pipe 22, the water enters the cylinder much faster than it can escape, the result being that after the Siphon is broken there is a supply of water in the tube, which, escaping through the pipe 22, passes to and fills the trap and partially fills the bowl `after the flush is completed. This part of my invention also operates without the use of valves, and is entirely automatic and reliable.
